Application med March 25,1914. serial No. 827,028.

To all whom 'it may concern: i i Y Be it'known that I, BERTHA S. ALsOP, a citizen of the United States of America, and residing at New York, inthe county of New York and State of New York, have invented new and useful Improvements in Bottles, of

which the following is a specification.`

One object of my yinventionis to produce a bottler which for all practical and; commercial purposes shall be non-refillable.

My invention has as a further object to prevent pouring of thecontents of the bottle incase it has been found ypossiblein-y some way to refill the once-emptied bottle. Even if refilled, it will be impossible to reuse the bottle. n .Y YThese objects are attained byy using a buoyant valve which consists usually of two parts, a floatable body and a flexible seal. A guard or guards arewalso provided for preventing mechanicalaccess to the valve or valves for the ypurpose ofy manipulation. Whenthe bottle is tipped up to pour out the liquid, the valve automatically opens` by gravity'andr the pressure of the liquid.

' When the bottle is stoodupright, the valve closes automatically by gravity.y The guarding means in the `preferred form serves also as a weight to assist in closing the valve and to vhold the valve positively closed when the bottle is upright. This positiveclosure of the valve obviates possibility of refilling the bottle in an upright position. The buoyant character of kthe `valve prevents refilling of the bottle in reversed positionl because in that case `any attempted inflow of liquid floats the valve to its seat. `When pressure is used in an attempt to force the liquid into the bottle, the valve is forcedbackward against a stop `and locked by the flexible seal so that itwill not open again. This prevents the emptying ofthebottle' in case it has been found possible to refill it and consequently prevents the reuse 'of the lbottle after it has been once emptied. y y i Figurefl, shows a cross section of the lneck of a bottle embodying one form ofthe improvements of my invention. Fig. 2,1is al view similar to Fig. 1, `but withthe'bottle tilted in the pouring position. Fig, is a drop View of the several parts which 'co operate to form the bottle closure. Fig. 4, is

a top plan view of these parts, omitting the valve seat and bottleneck. Fig. 5, is afi-ag-y mentary sectional View showing how 'the valve is locked after it has been forced back vreceive the "flexible seal.

by pressure Fig. 6 is a sectional view `of the neck of the bottle showing a slightly modified form of float.

As above indicated, the valve is buoyant and consists usually of two parts, a body part and a thin flexible seal 8 which normally engages with the valve seat. This seal may be made of any suitable material which is unaffected by the liquid contained inthe bottleand which will not affect the liquid. The necessary buoyancy may be given the valve by making the kvalve body hollow or of buoyant material, but in the present in stance, buoyancy is obtained by attaching a float 9 of cork or similar material tothe valve' body. The fioat may be attachedfto the valve body 'by simply forcing it into a seat or openingy 10 formed insaid valve body, the fioat in some cases having a re,

duced` lowei1 end 11 as indicated in Fig. 3 which fits tightly in the said opening. This reduced end of the float provides a shoulder 12, between which and the valve body they flexible seal may be clamped. This is a convenient and practical way for securing the valve body and flexible seal together. The edge of the valve body is preferably corrugated or fluted' as shown at 13 and lits loosely withinA the passage 14 in the bottle neck 15. The'edge of theseal 8 normally seats on the shoulder 16, at theouter end of passage 14. This shoulder, which in practice forms the valve seat, may be an integralipart of the bottle neck, but usually it is carried a separate annular valve scat member 18 which is engaged with the end of the bottle neck.

The outward opening movement of the valve is limited and controlled in the present instance by two movable guards, lan inner one 20, and an outer one 21. TheA inner guard, as clearly appears in Fig. 1, normally rests upon the flexible seal and therefore serves as a weight to hold thefvalve closed. .This guard member is shown provided ywith a central passage QZreceiving the` float portionk of the valve and it maybe recessed as at 23 on its lower end surface to This permits the guard to rest at its outer edge upon thevalve shoulder so that the valve is Vheld closedby the. guard 'without yrequiring the entire weight of the guard toi be borne by the flexible seal. yThefupper or! outer guard 21,'

in the illustration, rests directlyr uponxthe inner `giuird andnis provided mits sides with passages 25 permitting lateral access of liqnnicn. f

The movablev guards andthe valves are j y danger that va bottle which has been refilled' allfinclosed within a casing 9.9 which, rvas showmmay be in the form of a cap provided with'a'central pouring outlet 30, and

secured to the bottle neck-by a retainingy ring 3l.'v The upper end ofA theinner guard preferably engagesV the walls ofY the casing wit-h a loose sliding iit while the lowerend is somewhat'smaller, as shown. .-This permitsthe guard to have a tiltingfaswell as i a sliding valve-closing movement. .15.

Antortuous passage for theliquid is provided by grooving the ksides of the. inner1 guard member 20, as indicated 211332 andl p proridimg openings 33 in the outwardly {iaring; flange` 34- of the upper crown-shaped.

guard2l, so that the liquid is forced to] flow up along the sides of the inner guard and laterallyacross; the top of the Vupper guard to the pouring mouth'or outlet. The top of the upper-guard-may bedished as indicated to` ali'ordI alarge airspace and to-make more difficult ,e the insertion of an instrument 1n the outlet grooves.y

- For the purpose ofv guiding the valveixr erally across the top of the upperv guard te the central pouring opening. vThe ,weight of the guard or guards holds the valve closed and this renders it impracticableto. rell the bottle when inA an upright position. Reiillingby inverting.;andv dipping the bottle into a tankl is frustrated bythe liquid,y as it rises in the bottle, neck,` flowing laterally through passages2m5 and floating the valveup into engagement with its seat. yWhen. itv is attempted turetill the bottle by the application;r ofr external force, the` valve will be pushed in-Wardr and the edges ofi the seall 8y willV be. thereupon'. engaged beneath the, shoulderlO which' thereupony forms a valve seatin the.r passage 14;' so that itl will therealler'be, impossibley to pour out the liquid. rI;`his shoulder 4530' may as shown, bel carried the. separate annular .val've seat. member Instead of employing afloat formed as.v

described, a corlrof the proper size may be used-as.A indicated at; e3 in Fig.v 6. In this.

casethevalvefmay be guided by having Ythe largeriend of the cork engaging the walls of the ioassagei22-inthe guard.`V With this construction. itrispractically impossible to tampe1-:4 Withthe valve or relil'l the bottle and even if someliquid is; forcedI into. the vbottle no one who is familiar with ythe peculiarity of' this locking valve constructionfwill attempt to refill the bottle and there is no will be used to supplyY a substitute :tor the original liquid. e
